While I included Time Bomb since I feel that it is indeed a part of a Casefiles, I did not include The Alien Factor because, while I view it as a prologue to the Ring of Evil-Dead of Night it does not specifically mention any events from that case nor do any books mention any details of the events in TAF, However, if I had put it on the list, TAF would've been in the Top 5.

Also I did not include any Nancy Drew and Hardy Boys SuperMystery'88 books based on the explanation for The Alien Factor.

Also, I did not include The Crisscross Crime, for while it was originally meant as Casefile 130, it appeared as Digest 150. Had I listed it, it would've been in the Top 30.
